K: Matter/Basic information on the atom such as size and what it is made up of (protons + neutrons). Elements cannot be broken down.
W: How atoms were discovered/ atomic bomb? history/ elements.
L: elements make up compounds, to create new matter. Electrically charged atoms called ions combine to form compounds when two ions have opposite charges and attract. A chemical property occurs when one substance reacts with another and is chemically changed. = Compounds or elements that are mixed but not chemically bonded are called mixtures. If it is mixed evenly it is called a solution. Mass has three states: solid, liquid, gas, due to the amount of energy in matter.
